My invention has ior its object a new and improved support for tlzie spindle by which the basket is rotated, so that the spindle is supported, even though it may move oi" tend toniow,` out of a vertical line, diie to the unequal leading ofthe basket.

Y `ll. will first-describe the einloodii'nent @tiny invention illustrated drawings, in which*H Figure L1 is aii'ont elevation of my machine in the accompanying with a section lii'oken out of the dialin-pipe.

Fig. l2 is a Sectional plan taken on line 2 2, llign` l.v Fig. 3 is an enlarged sectional elevation taken on the line 3 3, Fig. 2. Fig. 4 is a detail showing ther bracket and bolt-head.

A is Vtlie base, i'iorn which project the legs Af, supporting the ouit` A, 'which curb suiam i'ounds the basket B, wliioh basket is oon-- stiuoted in. the usual. manner and supported oi' carried on the end of tlio s" idle C, The spindle passes tliougl'i the dsriving'pulley D, with which it makes a rotatable iit` The lower end of the spindle rests upon. the balls e and in the ball E, which ball til seated in a projection from the base 1i.

F 'i'epresents the arms ot spider, having the bearing ends interposed between Wliiol'i beating ends an the spindle @is tlie bronze bualfiing'f. The outei' ends oi. each oi the arms F of the spider have above them the Washer g, between Wliioli and the Was-lier g is the spring gt Below the spider is the Washer el, between which and the Washer g4 is the spring g5'. Thiough the spider arm, the Washers g o, spying g2, Washer g3, Washer g4, and spi'in C' extentie the bolt or guiding de vice ti, ifi/agli is tliieaded at its upper end The o'iiiieed o1-tion oiE the Washer g is also threaded anu turns on the tln'caded poi'tion of bolt G. A look-nut G" is seemed to the bolt above the, vreehei' g. The bolt aleo Y asses through tlie arm of a suppoit or taoket H, piojeeting imm the ieg it', and

pocket H east ,ice l use three devices and con ispaeed aiouud the lia-s the head G in the equa'4 with. the tiaoitxt. spideei l nootious, as des spindle As :may loe seen, in. this construction both the spiijloi' and i ai'ins and bearings on. the

idle ato integral with each otl ier, so that le iioin the tout is given oai a witospoodi l to tlie spideiH-ai'nis, eau ing an action either upon the tippe-' spi-ing oi' the low'ei s ning gi. los may be eeen, the n'zoveniient o the spindle causes an action. upon one o1' the otliei oi the springs lay' mail ofthe spidel'- aisne. ilius it the spindle tui-ns to move to the r lit the ie'lit-liaiui arm of the s idei' as o i l shown in the diawinos, will tend to compress the spring g5, while tile spideiearni on the left will tend to compi-ess the spring g2.- This inode ol. operation is facilitated `by making the bearing of the spidei on the spindleia oye liudrioal one, therebymaintaining vconsta-,nt

the angle of divergence ofthe spider fromlthe spindle, so that as thespindle tiltsi'om the vertical the outei end of tli'e arms will move up or down. Im practice this construction tends to maintain the equilibrium oi the spindle with great certainty. As may be seen, the bearing endf of. the spider is pro longed upwai'ffl and downward a distance suf- 'iieient to overlap the springs g2 and g5, this oonsti'uetion being effective to prevent oil in the beai'ino from iii/inv u on the rubbeifs o1' springs, which would tend to comode them..

prolonging these beaiingsf, as described,

they cover the springs, so that this danger of i the oil passing to tliein is obviated.

in iiraotioe the spi'ings g2 and are prefer .ably made of rubber, although they may be made in the form of a coil-spring oil any other desired shape.

Having now fully described my invention7 what l o`lain,fand desire to protect by liet-i ters Patent; is-

i. .lo a support for centrifugal extraotoi', in, combination, the basket-spindle, a spider comprising a 'plurality of projecting arms, and having a bearing on the spindle adapted to maintain substantially constant the angle off divergent/eef the spider and the spindle, a

guiding device for each arm along whieh the 05 outer end oi' the latter is adapted to move,

maintain substantially constant the angle df divergence of the spider from the' spindle, vsaid spider comprising a plurality of projecting arms, a guiding device for each arm which the outer end of the'arm engages, andV a pairof'yielding devices, one above and one below each of said arms', whereby, in the angular movement of the'spindle, the spider acts on'th'e'lower yieldin device only of one pair and the upper yiel ing device only mf 'another pair.

3. In a support for centrifugal extractor, in combination, the basket-spindle, aspider having a bearing on the spindleJ and comprising a plurality o'f projecting armsa guiding device for each arm, a support for the lower end of each-guiding device, the arm'loosely .surrounding the guiding device" substan tially midway between its ends, a yielding device above each arm, means to holdthe same from vertical bodily movement, and a yielding' device between each arm andthe support. v v Y 4.. -In a support for centrifugal extractor,

iii-combination, the basl';etspindle, a spider y havinga bearing on the spindle and compris' ing a plurality of projecting arms, a bolt suporting the outer endof each arm, a support or the lower end of each bolt, a Washer on l the bolt above the support, a spring on the bolt above s aid Washer, a second Washer on said bolt' above said spring, the outer end of the arm surrounding the bolt above saidsecond Washer, a third Washer on the bolt above the arm, a second spring onthe bolt above said third Washer, a fourth Washer on the bolt above said second spring, and Va nut on the bolt above said fourth Washer.

,-5. In a support for centrifugal' extractor, vin combination, a base, the basket-spindle, supported at its lower end on the base solas tobe free to oscillate thereon, the spindle be-V lngl confined from angular movement at no ot ler point, aspider' having a bearing on the basket-spindle adapted to maintain constant the angle of divergence of the spider rfrom the spindle, said spider comprising a plurality of projecting arms, a guiding device for the outer end of each arm secured to the base so as tov becapable of oscillating the-xeon and a pair of tension devices on each guidi-2' devicenne above and one .belc-f the corresponding, arm, whereby, in the angular movement of the spindle, an armacts on one or the'other of its corresponding tension devices a-nd the capacity for oscillation of the basket is limited only by the yielding capacity of the tension devices.

In testimony of vwhich invention I have l hereunto set my hand', aty Philadelphia, on

this 19th day of March, 1904.
